I’ll start this story in 1930, when Albert Einstein contributed his preface to Upton Sinclair’s Mental Radio— Upton’s published experiments in to telepathy:
“The results of the telepathic experiments carefully and plainly set forth in this book stand surely far beyond those which a nature investigator holds to be thinkable…. In no case should the psychologically interested circles pass over this book heedlessly.” Signed, A. Einstein.1
Around that same time Einstein was coming to grips with quantum mechanics and nonlocality. Quantum nonlocality2 indicates that things (photons, electrons, even molecules and small diamonds3 ) separated by space and time4 can still be linked, or entangled. Einstein was not put off by the possibility of telepathy, since —while telepathy seems to violate classical (Newtonian) mechanics— the notion of telepathy would violate no laws of quantum mechanics.
